JOHN OLOUGHLIN, OF BALTIMORE, MARYLAND.

CAN-SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 235,004, dated November 30, 1880.

Application filed August 27, 1880.

To all whom it may concern Be it known that I, JOHN OLOUGHLIN, of Baltimore city, State of Maryland, have invented certain new and useful Improvements in Gan-Soldering Machines; and I hereby declare the same to be fully, clearly, and exactly described as follows, reference being had to the accompanying drawings, in which Figure 1 is a front elevation of the device. Fig. 2 is a side elevation of the same. Fig. 3 is a perspective view of the solder-receptacle and its immediate adjuncts, and Fig. 4 is a transverse sectional view of the same.

My invention relates to machines for soldering the heads to the bodies of cylindrical cans, such as are commonly used for packing fruits, vegetables, &c.; and it has for its object to so combine a rotary can-holder with the soldering device proper that the heads are simultaneously soldered in place.

My invention therein consists in certain combinations of parts and details of construction not here necessary to be enumerated, as they are made the subject of the claims hereto annexed.

Proceeding to a description of the device, and referring to the accompanying drawings, A is the main frame of the machine, carrying uprights a a a. a, in which are bearings for the shaft B B. The part B carries a disk or plate, 11, on its end, and is furnished with pulleys d d for a driving-belt, in lieu of which latter, however, a crank may be used. The part B of the shaft has also a disk, 1), similar to that on the other part, B, and is susceptible of an endwise motion through its bearings, being normally thrown inward by means of a spring, 0, which carries the end bearing, 0.

A lever, D, pivoted to one of the uprights, serves to retract the part B of the shaft, when desired.

Both ends of the shaft are tapered, as shown, so as to revolve against their en (1 bearin gs with the minimum friction.

The plates 11 b are designed to clamp the heads against the body of the can and cause it to revolve with the shafts.

E is a rod, carrying at its upper end a pair of yokes, e e, in which the can-body rests, as shown, and it is normally thrust upward by (No model.)

means of a spring, 0, but is susceptible of being drawn down as the treadle F is depressed.

A A are uprights risingfrom the main frame A, and they are slotted as shown at A. Within the slots slide bars G G, to which is secured the solder-vessel H H. Springs 9 g serve to lift the latter, while rods f, connecting the bars G with a transverse piece, f, secured to the treadle F, admit of its being drawn down.

It will thus be seen that the yokes e and solder-vessel H rise and fall simultaneously.

Inasmuch as the description of the remaining parts of the device will consist wholly of detail, the operation of the parts already described may well be set forth here.

The can-body having been formed in the usual manner, and the heads having been placed thereon, the lever D is retracted, and the can is laid upon the yokes e, the part B of the shaft being caused meanwhile to revolve by power communicated through the medium of a belt or the pulley d or d, or in any other convenient way. The lever D is then released, and the part B of the shaft is impelled by the spring 0 toward the can, which latter is clamped between the plates 0 I) and instantly commences to revolve. The treadle F is then depressed, withdrawing the yokes e and bringing the solder-vessel H H downward until its irons I I are in contact with the seams, when a charge of solder is applied in a manner about to be described. The seams being thus soldered the treadle F is released, and the solder-vessel rises together with the yokes e. The part B of the shaft is then retracted by means of the handle D, and the completed can is removed to give place to the next.

Such is in general terms the operation of the machine.

Referring, now, to certain details ofconstruotion,formingimportant points ofmy invention, H H is the solder-vessel, made in two separable compartments, as shown, being connected by means of plates h, (see Fig. 1,) having slots through which the securing-screws h pass,the design being to admit of the adjustment of the solder-vessels to or from each other, so as to bring their irons over the seams of thecans; but a slight range of adjustment is necessary, as the difference in length between the stand ard one and three pound cans (practically the ultimate desired range) is but about seveneighths of an inch.

The side arms of the solder-vessel slide in sockets in the arms G, where they are secured by set-screws, as shown. All the connections of the solder-vessel, as at L L, are made to admit of adjustment in a manner clearly shown in the drawings.

Between the solder-vessels is a chamber, 0, having an opening, 0, for the burner, which is preferably a Bunsen gas or gasoline jet, so as to give a sootless non-luminous flame. The burner is not shown, and any suitable form of burner may be used.

On either side of the chamber 0 are the chambers proper, which contain the molten solder. In each chamber is a piece, P, through which the iron I, of copper, is inserted.

Above the vessel H are pivoted levers j, operatin g, respectively, as levers of the first and second order with respect to the plungers J J, to which they are connected, and which reciprocate in the pieces P. The levers are normally lifted by springs K, attached to the arms L, whereby the rear plungers. J, are also lifted, allowing the molten solder to flow through holes 0 and fill the chambers S and tube S. This amount of solder constitutes the charge which is applied to each head-seam, which charge may be regulated at will by means of a screw-plug,p, which is raised or lowered, as desired, in the chamber S.

As the leve'rj is depressed through the medium of the rods m, bar N, and treadle M, the plunger J is depressed, closing the communication between the solder-chamber and the chargechamber S, and simultaneously the plunger J is lifted, allowing the solder to flow out of the discharge vent, duct, or tube S upon the front edge of the iron I, which latter is grooved, as at 6, Fig.1, to form a little gutter to conduct the solder to the point of the iron where it is in contact with the can. The curved face of the iron is flanged (see i) to lit the flange of the can-head, and the can revolves in the direction of the arrow, carrying the solder under the iron. The latter is secured by a set-screw, I, and is fed downward as it wears away.

To supplement the foregoing description of the operation of the device it is only necessary to add that as the solder-vessels are drawn down by the lever F to the can-seams the lever M is depressed, causing the charge of solder to How. When theleveris released the plunger J ascends and allows the charge-chamber to be refilled.

It is obvious that the lever j might be connected with any stationary or oppositely-moving part of the machine by cords or otherwise, so as to automatically open the discharge-orifice of the solder-chamber as the vessels descend; but I do not believe such to be desirable, as the operator who places the cans on the yoke and removes them when completed has both hands free pending the descent of the solder-vessel, and it is preferred that he shall intelligently operate the solder-discharge rather than rely on the machine to do it.

It is obvious that instead of causing the soldering-irons to descend into contact with the seams, the motion may be reversed, the can being made to rise to meet the irons; but the described construction and mode of operation is to be preferred.
